Aetolian League

The Aetolian League was a confederation of tribal communities and cities in ancient Greece and Aetolia, existing from the 4th century to 188 BC; Thermon was its capital. It was established in opposition to Macedon and the Achaean League, and it occupied Delphi in 290 BC and came to control all of Greece outside Attica and Boeotia by the end of the 3rd century BC. The Aetolian League was regarded as semi-barbaric and reckless, and it was driven into an alliance with the Roman Republic due to its conflicts with Macedon. This ultimately led to Rome's invasions of Greece and its absorption of the Aetolian League.
